General annotation (Comments)

Function

Enzyme with a broad specificity.

Catalytic activity

A phosphoprotein + H2O = a protein + phosphate.

Cofactor

Binds 2 magnesium or manganese ions per subunit By similarity.

Subunit structure

Monomer By similarity.

Sequence similarities

Belongs to the PP2C family.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Note: Additional isoforms seem to exist. Isoforms appear to differ in their C-terminus.
Isoform 1 (identifier: P35815-1)

Also known as: Beta-1;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P35815-2)

Also known as: Beta-MPP;

The sequence of this isoform differs from the canonical sequence as follows:
     379-390: GAGDLEDSLVAL → FYQPSTPYSDNVSYYEWQT
